Implications of the use of vascular CDL in hemodialysis patients: analysis of echographic insertion sites (original) (raw)

Jornal Brasileiro de Nefrologia, 2014

Abstract

Chronic renal failure is a disease which prevalence has been increasing in Brazil. Hemodialysis is their primary therapeutic modality and arterio-venous fistula their preferential access. Nevertheless, many patients require the use of double-lumen catheters, either as permanent or temporary access. Vascular complications related to this procedure may occur, and their best method of non-invasive analysis is ultrasound analysis. To analyze the complications by the use of double-lumen catheter in patients with chronic kidney disease on hemodialysis, at "Santa Casa de Misericordia de Ponta Grossa" hospital, through eco-Doppler exam. Observational research, analytical, case-control type, to obtain data we used TASY®, interview, physical exam and imaging (eco-Doppler). None of the variables was significant isolated as a predictor of vascular impact in eco-Doppler, which detected changes in 31.25% of the cases. Physical exam showed poor accuracy compared to Doppler capacity to detect complications (K = -0.123). We conclude that the vascular effects of the use of CDL are frequent (31.25%). Manifesting itself in the form of occlusions with/without recanalization and stenoses. This leads us to required a prior analysis of the insertion site with Doppler, in order to avoid unnecessary procedures and possible complications.
